Definitions
- the application EP2789591 indicates that the non-circular cross-section glass fibers make it possible to improve the mechanical properties, the dimensional accuracy and the warpage of resins reinforced with said non-circular section glass fibers. This is due, according to this application, as regards the improvement of the mechanical properties, the fact that the non-circular section glass fibers have a greater contact area than the circular section fibers. As regards the improvement of the dimensional accuracy and the warping, this is due, again according to the application EP2789591, to the fact that the non-circular section glass fibers are oriented less in the direction of the flow. as circular section glass fibers and therefore tend to be more bidimensionally oriented than circular section glass fibers in the injected part.
- Meta-xylylenediamine (MXD, CAS No. 1477-55-0) may be used alone or in admixture with para-xylylene diamine (PXD, CAS No. 539-48-0), but in the latter case, and in the whole description, the MXD must be in majority compared to the PXD.
- PXD para-xylylene diamine
- the MXD is used alone and the composition is therefore devoid of PXD.
- MXDZ can be a mix of MXDZ.
- the L / D ratio is equal to about 1.
- polyamides within the meaning of the invention refers to polyamides which have a melting point (Tf) and a melting enthalpy ⁇ > 10 J / g, in particular> 12 J / g, and a glass transition temperature (Tg) as determined by DSC according to ISO Standard 1,1357-1: 2009 and ISO 1,1357-2 and 3: 2013, at a heating rate of 20K min.
- Tf melting point
- Tg glass transition temperature
- said at least MXDZ consists of 0% to 49% by weight of MXD6 and 51 to 100% by weight of MXD10 and said aliphatic polyamide A obtained from the polycondensation of an XY unit is comprised of 0 to 49% by weight of PA610 and from 51 to 100% by weight of PA1010.
- A injected plate 11 or 12 whose warpage is limited and less than 1 mm
- B injected plate C1 or C4 whose warpage is very large and greater than 5 mm.
